Description

technical field [0001] The invention relates to the technical field of machine waste gas treatment, in particular to a VOCS waste gas collection and detection device and a method for using the same. Background technique [0002] VOCs are a class of volatile organic compounds with a boiling point of 50°C to 260°C and a saturated vapor pressure of more than 133.3Pa at room temperature. It is very harmful to human health and the ecological environment. At present, VOCs treatment technologies include two categories: destruction and recycling. The recycling technology is widely used due to its simple process, good economy and relative maturity. The principle is to use activated carbon to fully adsorb VOCs. The VOCs adsorbed on the activated carbon are desorbed, and then condensed and liquefied to realize recycling. [0003] In the prior art, the utility model patent with the patent application number CN202020241983.9 discloses a VOCs exhaust gas treatment collection box for spra...
